1. Значение выражения:
\( (3\frac{5}{8} - 1\frac{1}{6}) : (-1\frac{3}{8}) \)
- \( 3\frac{5}{8} - 1\frac{1}{6} = \frac{29}{8} - \frac{7}{6} = \frac{29 \times 3 - 7 \times 4}{24} = \frac{87 - 28}{24} = \frac{59}{24} \)
- \( -1\frac{3}{8} = -\frac{11}{8} \)
- \( \frac{59}{24} : (-\frac{11}{8}) = \frac{59}{24} \times (-\frac{8}{11}) = -\frac{59 \times 8}{24 \times 11} = -\frac{59}{3 \times 11} = -\frac{59}{33} \)
Ответ: -\( \frac{59}{33} \)
